Then every positive semidefinite meromorphic function on X is a sum of 10 squares of meromorphic functions on X. As a consequence, we provide a real Nullstellensatz for (global) real analytic surfaces.doi:10.1007/s12220-021-00721-1José F. Fernando...
positive semidefinite半正定 1.Under the cases that the objective function is positive definite or positive semidefinite, the necessary and sufficient conditions to characterize global optimal solution are obtained.假定约束是可行、规范的,对于目标函数为正定或半正定的情形,得到了全局最优解的充要条件。 2.Gi...
The problem of checking stability using positive semidefinite Lyapunov functions has been considered in Bensoubaya et al. (1999) for continuous-time systems and in Grizzle and Kang (2001) for discrete-time systems. The idea is to use a Lyapunov function V(x), which is positive semidefinite, ...
